Search for: Subunit vaccines are vaccines that use only part of the disease-causing virus. This strategy is used most often when one part of the virus is responsible for creating disease. The part responsible for creating disease is a protein, which we call the antigen. An example of the recombinant subunit vaccine is the hepatitis B virus vaccine.
In some cases, these vaccines use epitopesâthe very specific parts of the antigen that antibodies or T cells recognize and bind to. Because subunit vaccines contain only the essential antigens and not all the other molecules that make up the microbe, the chances of adverse reactions to the vaccine are lower.
